Seismicity has remained at low levels over the past 24 hours. Elevated surface temperatures, consistent with cooling lava flows, were detected in satellite data over the past 24 hours, although, views of the volcano in satellite data and in the Cold Bay web camera were often obscured by clouds. It remains possible for eruptive activity to resume at any time and seismic activity remains slightly elevated above background levels.

Low-level eruptive activity consisting of lava effusion and minor emissions of steam and ash continues. Nearly continuous, gradually fluctuating volcanic tremor and occasional explosions have been observed in seismic data over the past 24 hours. A water-rich plume likely containing minor amounts of ash were observed in satellite images this morning extending for 45 km (28 miles) to the northwest at an estimated altitude of less than 15,000 ft (4.5 km) above sea level. Elevated surface temperatures at the intracaldera cone also have been observed in satellite data. Web camera views from Perryville have been obscured by clouds and fog.
